Answer:
Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases green house gas emission.Typical greenhouse gasses are water vapour,methane and CO2.
Most of the Earths heat are supposed to escape into space however green house gases present in the atmosphere interferes with this process and traps the heat within the Earth leading to global warming.
Global Warming has catastrophic effects to the Earth.Increase in the Earths temperature will melt the ice caps accumulated at the poles leading to a rise in sea levels which will inevitably cause flooding in regions below sea level as well as many other disastorus events.
